SOLDERING IRONI applicati@ iiieaseptemter 10.1921. serial No. 499,597.

' To. aZZcctom 'it may cof/wem.'

Be it known'. that l, PAUL L. Simoon, a

citizen of Canada, residing at Theresa, in the y.

`lProvince of Saskatchewan, Canada, have invented certain new and useful .improvements yin Soldering irons, or' which the following is aspeciiication.

This invention relates `to soldering irons,` havingmore particular reierence to a solder-` ing iron in whichthe bolt and its heater are f comprised in a singleI self-contained implement.

,The invention has i'or an object to provide a'soldering iron ofthis'type of` simple construction `and in which .the heating means i willact leiiciently to heat the bolt.`

For further comprehension of' the invention, and of `the objects and advantages thereof', reference ywill be had to the follow-V ing description and appended claims, and to y the accompanying drawings in which the various novel featuresof the invention are more particularly set iorth.

Fig. 1 of the drawings is an. axial sec` tional view of `the heating element of asoldering iron constructed according to the invention, the bolt being omitted.

FiO. 2 is a sideelevation oi' the complete i iron.

#4 or rig; 2.

adapted to contain a suitable 'fuel liquid` such as gasoline or other oil, being provided on one side with a filling opening closed by a p `screw cap 11, and having one head in the 4Hiorm of a removable cap 12. Fixedto this' cap 12, and projecting therefrom Iaxially into the tank 107 is a ycylinder 13 lutilised fory pumping air into the tank` n Within this cylinder 13 is a piston having a one-wayvalve, this piston being fixed to a rod 14 extendingthrough the cap 1.2 and having a handle 15 on its outer-end. The piston comprises a body 16 of lessdiameter than the inside of the cylinder 13 and having adiminished extension on whichis placed a i packing ring 17 held in place by a nut or washer 18. Extending through the piston body is a passage 19 enlarged at one end to form a valve chamber containing a ball valve 2O acting in a well known lmanner to displacement.`

prevent flow of air through the passage 19,

i back towardr thehandle 15.`

Extending Iacross the. cylinder 13 adjacent its inner end is a partition 91 forming a seat for a `valve 22 which is pressed to closedipof sition by a spring 23 and acts to prevent back flow of air in the cylinder. Formed in the inner and outer ends oi' the cylinder are air holes 24 and 25 respectively'ithrough which the air is drawn into the cylinder and discharged into the tank 10.

Formed inthe end of tank opposite to i `the cap12is a circularblock 30 into which is screwed the nipple 31 ofaburner element.

a lock nut 32 holdingsaid nipple against whichthe nipple projects,y a hollow trans verse boss 34 being formed on the body 32 at this end. Extending through the block and nipple 31 is apassage 35 leadinginto the chamber 36 formedin the boss 34, `while a The burner element` comt prises Ia cylindrical body 33 from one end of second passage` 37I offset laterally from the passage leads forwardly through ythe burner body 33, a tube 38 being fitted into the outer end of the passage 37 this tube 38 extending into an elongated cap 39 screwed onthe end of' the burner body and providing a compartment inthe burner elementk in which the fuel is heated. Threaded into the boss 34 is a needle valve 40 which controls `the i'ilow of liquid between the passages 35 and 37. Connected to the inner end of passage 35 is a tube 41 which' extends rearwardly in the tank 10.

Formed on the forward end of the member 32 is an offset 45 provided with a burner tip 46, this tip being enclosedby a sleeve 47 `screwed `on to the offset and having a series of air intake passages 48` in its side walls. Extending through the burner'tip 46 is a small passage 43 communicating at its krear end with a larger passage 49 forming a chamber for a needlevalve 50 screwed into the rear endoi' the oii'set 45. An angular `passage 51 leads through the member 33 froni the interior of the cap 39 to the valve chamber 49. f

The burnerA member just described is `adapted to be enclosed by the `bolt which is `in the forni of an elongated shell 55 pre* f v,senting at one end acollar `56 which ts over the end of the tank 10 and may be i secured thereto by a set screw 57. The body `oi the shell is of segmental cross section,

being thus open on the underside in registry with the burner element, While the liront of the shell is made solid and of tapering form as shown. Formed in the sides of the shell .y

55, and spaced both4 longitudinally and transversely thereof, are air' openin'gs 58.l

It is believed that the manner of operationand use or my improved soldering iron will be readily understood `from the above description, the :'f'uel liquid being placed in tank and air pumped thereinto' by recipro-y cat-ing the piston in cylinder, the air passing through the piston on its rearward stroke and beingorced into the ytank on the forward stroke 'of the piston. y The liquid 'from the tank first passes into the chamber formed bycap 39 whereit is heatedby the heat of theflame issuing from the tip 46, passing inally through passagewltothe burner tip. When the burner is Ifirst started `the cap is initially heated by any suitableV mental cross' section presenting a collar at` one end litting` over and `secured to the end of the Atank connectedto Vsaid tank, ya burr'ie'rl body connected at'its rear end to saidtank and extending Within said hollowbolt length' tudinally thereofl and presenting at its for thefllnited States is as fol si gnature.
